Be it known thatI, Anevwltoennaa citizen oi the United States, residing at San Francisco, in the county of San Francisco and State 01 California, have invented new and useful improvements in Fuel Mixers :lor Internal-Combustion Engines, of which the following is a specification.

This invention relates to internal combustion engines, and has particular reference to a mixing device applicable to en gines of this type.

The primary object of this invention is to provide a device of the above mentioned character adapted to be installed at the entrance of the intake manifold of internal combustion engines, particularly those used in automobiles and motor boats.

Another object of this invention is to provide a mixer including a base portion for a spindle which has mounted thereon a plurality of radial rotating blades functioning to break the gasoline into the finest particles as it comes from the carburetor in a vaporized form, and thus furnish a completely vaporized mixture. I

Other objects and advantages of the invention will be apparent during the course of the following description:

in the accompanying drawings forming a part oi this specification and in which like numerals are employed to designate like parts throughout the same, I

Figure l is a side elevation of an automobile engine showing my device in position,

l igure 2 is a sectional view taken on the line of Figure 3,

lliguro 3 is a top plan view or the device, and

Figure 4 is a horizontal sectional View taken on the line 4c l of Figure 2.

in the drawings wherein for the purpose of illustration is shown a preferred embodiment oi my invention, the numeral 5 designates an apertured flanged portion of the curbiu'etor, while the numeral 6 designates an apertured flanged portion of the mani- :l old. Disposed between the two flanged portions and suitably retained'therein by fastening elements T, preferably bolts, is a base member 8 having a centrally located opening 9 and an internal beveled wall formed therein. integrally formed with the base member 8, is an arm 10 terminating in a circular bearing 11 which is provided oi the spindle.

with" an internally threaded opening 12 'a-dapted "to" receive a spindle 13 therein,

3 threaded as shown at 14-.

The numeral 15 designates a cap adapted to be detachably fastened 'to one extremity Disposed between the bean ing 11 and the cap l5,and loosely mounted on the spindle for rotation thereon, is a rotary element including a hub portion 16 and a plurality of radial blades or fan shaped mixers 17. The blades are angularly disposed on the supporting hub and are so formed that vapors contacting therewith will tend to whirl outwardly after being thoroughly mixed and will more surely contact with the heated walls of the intake pipe and expand outwardly, thus producing the greatest possible heating efi ect before reaching the engine.

For the purpose of applying moisture to th device, an angular tubular element 18 extending from the radiator enters an opening 19 formed in the base member 8, and thus serves to allow steam coming from the radiator to supply the moisture above referred to.

it will be obvious that the blades are so proportioned that the diameter of the blades conform to the opening formed by the restricted wall of the base member, and thus the full eii ect or" the incoming passing currents of gas will be felt on the blades and that the hub portion 16 with its radial blades is accurately centered in the intake pipe and thus a proper centering of the fans is attained.

In the construction of the device, as far as possible, the finest steel is employed, in order that the highest temperature may be obtained, and the fouling and corroding of the parts may be minimized.

From the description taken in connection with the drawings. it will be obvious that I have provided a mixer comparatively economical in manufacture, simple in construction, compact in the arrangement of its parts, and a mixer which is applicable to standard types of engines without materially altering the construction thereof, and a device which serves to adord complete combustion, at the same time minimizes the use of fuel.

It is to be understood that the form of my invention, herewith shown and described is to be taken as a preferred example of the same, and that various changes in the shape, size and. arrangement of parts may be resorted to Without departing from the spirit of the invention, or the scope of the subjoined claim.

Having thus described my invention, I claim:-

A device of the character described, comprising an apertured base member, an arm extending into the aperture formed in said base and terminating in a bearing, a spindle mounted in said bearing, a rotary element provided With radial blades and adapted to rotate on said spindle, means entering said base member for the purpose of distributing moisture to the'blades of said rotary element, means for retaining said rotary element on said spindle, said aperture on said base member being tapered in such a manner that its smallest diameter is equalto the diameter of said rotary member.

In testimony whereof I aifix my signature.

ABBY ROGERS.
